MySQL is fast enough, usually has enough features, I know how to tune it and queries, and I normally only bump into 2-3 things in a project which would've been easier with PostgreSQL. And can work around them.
The backwards-incompatible SQL_MODE changes between MySQL 5.6 and 5.7 made me reconsider, as legacy apps needed updating.
tl;dr: yes. But PostgreSQL would be easier for some items
